PHYSICAL CHARACTERISTIC, NUTRIENT AND QUERCETIN CONTENT OF OKRA (ABELMOSCHUS ESCULENTUS L.) WITH DIFFERENT HARVESTING AGE
Okra has been known to posses several benefits for health, such as controlling blood glucose, improving lipid profile and as it contains bioactive compound like quercetin which plays an important role as antioxidant. Biofortification is a method to increase the quality of crop such as vegetable, therefore it can contain higher bioactive compound. Hybridization is one of the method of biofortification, and from it generated okra genotype Naila. The purpose of this study was to determine the optimum harvesting age of okra based on physical characteristic, nutrient and quercetin content. Harvesting age was selected from 5 days, 7 and 9 days after its flower bloomed. Physical characteristic measured in this study such as length, diameter and weight of each okra. Another parameter analysed such as color (L*, a*, b*, C*, H*) and texture (hardness), nutrient and quercetin content. There was significant difference on length, diameter, weight and also hardness (p<0.05), but it wasn’t vary on color. Moisture content was decreased but insoluble fiber increased, concomitant with increasing of harvesting age. Based on those parameters, the optimum harvesting age selected was 5 days.
